In this week of WWDC, Apple also started the testing phase of Mac OS X 10.5.8, with the first of manybuilds which should be released to developers.
If the update was already seen by some with a tone of importance for starting the final stretch of Leopard on the market, now it gets even more complicated: it will be one of the last if not the last to be delivered with PowerPC Macs support. After that, the focus will be full on the installed base of Intel Macs, which will host Snow Leopard later this winter or early spring, in the northern hemisphere.
It is not known whether other major updates will be released for the old Leopard after the release of Snow Leopard, but it is certain that Security Updates currently released for Tiger and Leopard will continue to roll for quite a while, as Intel Macs are being updated. After that, it is difficult to predict what the future of the system will be that runs on Apple machines over four years old, including the G5s, which were once all-powerful for Apple.
Sources with knowledge of the matter say that more than 10 betas from the update have been released. Their internal code would have changed from class 9Jxx to 9Lxx, while 9Kxx is installed on the new MacBooks released yesterday.
There is no information about which fixes may come in this update. However, the fact is that Mac OS X 10.5.7 has left some very inconvenient marks for several users. Network failures, crashes due to numerous causes, problems with DVD playback and loss of Bluetooth connection are some examples. Did I forget any?
